Metro Boston, north shore and metro west: There will be a temporary reprieve from the arctic cold on Saturday. Temperatures are expected to climb into the low and mid 30s but a gusty wind from the south and southwest will bring a blustery feel to the day as a cold front approaches. A few bands of snow showers may cross the area through the afternoon, perhaps coating the ground in some locations with up to an inch possible through the far interior. This activity comes to an end in the evening as the front briskly moves through the area. To the rear of the frontal passage will be another blast of cold air for Sunday as temperatures struggle to reach 20 degrees. Gusty winds will make it feel even colder.
The most noticeable feature over the next several days is going to be the winds. They will howl out of the south and southwest Saturday, backing to the west on Sunday, returning to a southwesterly direction Sunday night and Monday and back to the west Monday night into Tuesday. The winds will be very active through this period, gusting to 30 and 35 mph at times, as systems are on the fly and will move through here very quickly both Saturday and Monday. So, any spike in the thermometer, notably Saturday and Monday, will not be as appreciated as it could be due to the gusty winds.
A fast moving disturbance will emerge out of the northern Plains and into the eastern Great Lakes by Monday morning. This will move to our north introducing another strong southerly flow with temperatures rebounding into the 30s on Monday. This system will rapidly move into southern Canada during the day and swing a strong cold front through here by nightfall. Behind the front temperatures crash once again with Tuesday another bitterly cold day as temperatures probably remain in the teens through the day.
During mid week an ocean storm passes to our southeast with early indications showing a near miss for our area.
